We explored optimizing geometric parameters \ufffd attack angle (0\ufffd\ufffd45\ufffd), cutting edge width, and profile shape (straight, wedge, radial) \ufffd to boost efficiency and cut energy use. Numerical simulations via SolidWorks finite element analysis (FEA) used a tetrahedral mesh (0.1\ufffd0.5 mm elements) and the Mohr-Coulomb criterion to model cutter interactions with rocks like limestone, sandstone, and granite. Boundary conditions fixed the rock base, with a friction coefficient of 0.3\ufffd0.5 and cutter speed at 0.1 m\/s. Results show geometry drives cutting forces, stress distribution, and energy efficiency. Wedge-shaped cutters at 15\ufffd30\ufffd reduced energy use by 20% for softer rocks, outperforming the 10\ufffd15% savings in prior studies. Radial cutters excelled for granite, balancing stress and wear. These findings align with trends in other researcher works but offer enhanced efficiency. Practically, this optimizes tool design, cutting costs and boosting durability for geological drilling, tunneling, and construction. Applications extend to rotary, percussive, and directional drilling across materials like concrete, improving efficiency, tool life, and project timelines in diverse industries.<\/jats:p>","DOI":"10.5593\/sgem2025\/1.1\/s02.16","type":"proceedings-article","created":{"date-parts":[[2025,11,22]],"date-time":"2025-11-22T09:16:32Z","timestamp":1763802992000},"page":"121-128","source":"Crossref","is-referenced-by-count":0,"title":["INFLUENCE
